Frigidaire Refrigerator HI TEMP Error: Causes and Fixes
Is your Frigidaire refrigerator showing HI TEMP? Learn what the warning means, why temperatures rise, how to troubleshoot it, and when to call a technician.
ERROR CODES
9/12/20263 min read
A HI TEMP warning on a Frigidaire refrigerator means the appliance has detected that the temperature inside the refrigerator or freezer is higher than the expected range. It is a temperature alert rather than a traditional component-specific error code.
This warning should not be ignored, particularly if it remains on the display for an extended period. A refrigerator that is too warm may not be able to keep perishable food at a safe temperature.
First, Check Which Compartment Is Warm
The first step is to determine whether the problem is affecting the refrigerator compartment, freezer compartment, or both.
Refrigerator Is Too Warm
Possible causes include:
Door not closing completely
Warm food being added frequently
Blocked air vents
Incorrect temperature setting
Poor airflow
Faulty temperature sensor
Cooling-system problem
Freezer Is Too Warm
A warm freezer can be caused by:
Door left open
Excessive frost buildup
Blocked vents
Dirty condenser area
Fan problem
Compressor or sealed-system issue
Temperature-control problem
If both compartments are warm, the problem may involve the refrigerator's main cooling system or power supply.
Quick Troubleshooting Checklist
Work through these checks before assuming a major component has failed.
1. Make Sure the Door Is Sealing
Check that nothing is preventing the door from closing.
Look for:
Food packages sticking out
Drawers positioned incorrectly
Damaged door gaskets
Ice preventing the freezer door from closing
A door that remains slightly open can allow warm, humid air to enter continuously.
2. Check the Temperature Settings
Make sure the refrigerator has not accidentally been set to a warmer temperature.
If the controls were recently changed, give the refrigerator enough time to stabilize before deciding that there is a cooling failure.
3. Keep the Air Vents Clear
Cold air needs to circulate throughout the refrigerator.
Do not pack food tightly against the interior vents. Blocked airflow can create uneven temperatures and contribute to a HI TEMP warning.
4. Check for Excessive Frost
Look inside the freezer for a thick layer of frost or ice.
Heavy frost can restrict airflow and prevent cold air from circulating properly. If the freezer is heavily iced over, there may be an underlying defrost problem.
5. Listen for the Fans
The refrigerator normally uses fans to move air through the cooling system.
If you don't hear normal fan operation—or hear a fan repeatedly trying to start—there could be a fan, wiring, or control problem.
What About a Recent Power Outage?
A power interruption is one of the simplest explanations for a HI TEMP warning.
After power is restored, the refrigerator may need time to bring the compartments back down to their normal temperatures. The warning may remain until the appliance reaches the required temperature.
If the refrigerator has been without power for a significant period, check the temperature of perishable food rather than relying solely on the display.
When the Warning Doesn't Go Away
If the refrigerator continues displaying HI TEMP after adequate cooling time, investigate further.
Potential causes include:
Airflow problem → Fan failure → Defrost issue → Temperature sensor problem → Condenser problem → Compressor or sealed-system fault
The exact cause depends on the Frigidaire model and the symptoms you are experiencing.
Food Safety Matters
A HI TEMP warning is not just a convenience issue.
If the refrigerator or freezer has become significantly warmer than normal, check the actual temperature with an appliance thermometer. Don't assume that food is safe simply because the refrigerator is still running.
When in doubt about food that has been held at unsafe temperatures for too long, it is safer to discard it.
When Should You Call a Technician?
Professional service is a good idea when:
HI TEMP remains after the refrigerator has had time to cool.
Both refrigerator and freezer sections are warm.
The compressor does not appear to run.
Fans aren't operating normally.
Heavy frost repeatedly returns.
The refrigerator makes unusual noises.
Temperatures continue to rise despite normal settings.
The warning repeatedly comes back.
A technician can test the fans, sensors, defrost components, compressor, control system, and sealed refrigeration system.
Bottom Line
The Frigidaire HI TEMP warning means the refrigerator or freezer temperature is too high. It can be triggered by something as simple as a door being left open or a recent power outage, but persistent high temperatures can also point to a cooling-system problem.
Start by checking the doors, temperature settings, airflow, frost buildup, and power supply. If the appliance cannot return to its normal temperature or the HI TEMP warning keeps returning, professional diagnosis is recommended.
Tip: The exact warning behavior and temperature thresholds can vary by Frigidaire model, so use the model number to check the owner's manual for model-specific instructions.
